MPluginManager – Mousepointer disappears – MeldaProduction Forum

Not sure if it was you, we get similar report via the support, so here is the reply, it may help you and others as well:
Possible causes:

1. Corrupted application window state / cache Please try closing the app, then delete the folder: C:\Users\\AppData\Roaming\MeldaProduction\MPluginManager

After that, start the application again. It will recreate the default configuration.
2. Multi-monitor setup or custom DPI scaling
Do you use multiple screens or custom scaling (DPI) settings in Windows?

These can sometimes cause UI rendering issues such as a missing cursor or misaligned input.

3. Compatibility mode issue
Try running the application in compatibility mode:
Right-click the app executable
Select Properties → Compatibility
Try enabling Disable fullscreen optimizations and DPI settings of the app

4. Try update/reinstall you GPU drivers.

5. Finally, please try restarting the computer after applying these steps, as it may reset the graphics/UI state.

If nothing helps, we can instruct you how to disable GPU acceleration for the app, which will also potentially help.
